Hi, scarletrose.
As others noted, only you can decide. But I will say your description sounds A LOT like me—and yeah, I'm an alcoholic, no question about it.
Regardless, I think Terminally Unique pretty much nailed it. It seems like you have every reason to quit regardless of what label you slap on it. If you find it's no big deal to go without for a few months, then great. But if that's a challenge... well, I think the harder it is to quit, the more we need to quit. At least that's my experience.
Glad you found us. You'll get a lot of info and support here.
